Between the lay-flat apparatus and the conveyor there is disposed at least one pulley roll and one overturning bar for turning the tubular web 180 DEG with simultaneous change of direction, which, like the lay-flat apparatus, are supported in an apparatus frame for pivoting reversingly in a horizontal plane about the axis of the delivered tubular web. The lay-flat apparatus, the pulley roll and the overturning bar are held for their reversing pivoting movement on swivel rings disposed one over the other and supported directly on one another through interposed rolling bodies which form together a swivel ring stack rotatably mounted in the apparatus frame and compressively stressed, whose inside diameter is at least equal to the maximum working width of the apparatus.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a tube of a synthetic resin film produced by an extruder equipped with a blowing head arranged at a fixed position according to the preamble of claim 1. Correction device for

When manufacturing synthetic resin film tubes by the blowing method, thickness tolerances cannot be avoided. this is,
For example, on the basis of the usual manufacturing tolerances in the blowing head of extruders used for the production of films, internal and external cooling effects in the calibration means through which the expanded circular cross-section tube passes following the extrusion process. Or it is caused by other external circumstances. When this type of tube is wound in a winding device in a flattened state, a thickness tolerance will be added unless appropriate precautions are taken.
An annular beat is formed on the film roll. This annular beat will result in permanent deformation of the film in its vicinity, which will make printing and subsequent processing of the film difficult.

So-called flip straighteners for tubes have been developed as a suitable precaution to prevent the formation of annular beads on film rolls. In the case of the same device, the reversal movement of the part of the device involved in the flattening of the tube causes a periodic variation of the fold edges that are formed during the flattening of the tube. With this, the possible thickness tolerances are appropriately distributed over the width of the flattened tube band. In this way, during subsequent winding of the flattened tube in the winding device, the formation of annular beads on the roll due to the addition of film thickness tolerances is avoided. In this case, it goes without saying that the turning angle of the reversing movement must be made sufficiently large.

PRIOR ART In a known similar type of device (West German Patent No. 2035584), the squeezing rollers of the leveling device are invertedly swiveled about 360 ° about the axis of the fed tube. Be punished. It has been found that the swivel angle of the reversal movement is suitable for the majority of cases using reversal straightening devices. In this case, in addition to the two diverting rollers for diverting the tube band by about 180 °, two turning rods for diverting the tube band by about 180 ° while simultaneously changing the direction are provided in a staggered manner. Has been. On the other hand, if the turning angle of the reversing movement of the flattening device with squeezing rollers is less than 360 °, the only turning rod between the two turning rollers is to treat the tube in the reversing part of the straightening device. Is enough.

In the known similar type straightening device, when the turning roller and the turning rod are pivotably supported in the device about the axis of the supplied tube, the turning roller and the turning rod have respective axes. It is arranged so as to extend in contact with each circle centered on the rotation axis of the flattening device. In this case, the diverting roller lies, in all possible operating positions, radially outside of the part of the turning rod around which the tube winds. The swivel angles of the diverting rollers and the deflecting rods decrease with distance from the flattening device, and the film tube moves with the diverting rollers and the deflecting rods and the transport device in place for unloading the flattened tube. In between, they are transferred in horizontal planes parallel to each other. This achieves the low overall height of the inversion system. In this case, furthermore, by making the radius of the circle drawn by the orbit of the turning axis of the turning rod to be π / 4 × the turning rod diameter, the plastic resin film-the lateral direction of the tube during turning of the reversing system. Is prevented from moving. In this case, it is clear that the intersection of the respective central axes of the tube band towards the turning rod and the tube band away from the turning rod lies on the pivot axis about the center of the reversing system. During the reversing swivel movement, it is ensured that the tube strips open and close like scissors about said swivel axis, and thus theoretically both tube strips have the same frictional forces in opposite symmetrical directions. Will work. In this way, from such an idea, the axial movement of the turning rod of the tube due to the frictional force acting on one side during the reversing operation is avoided.

In the known straightening device, the leveling device, the diverting roller and the turning rod are supported on a relatively thin central axis in order to carry out a reversing pivoting movement. The central axis extends along a vertical extension of the axis of the supplied tube band, and is rotatably supported on the device base. In this case, the total weight of the reversing system is carried by the central axis, so that the reversing system is very vibration and vibration prone. Such vibrations and vibrations can be very sensitive, for example, when an operator moves on the attached ramp of the straightening device (especially if the straightening device is placed considerably higher due to the long vertical straightening path). To do. Furthermore, due to the support shaft located in the center of the device on the extension of the supplied tube axis, the installation and maintenance of the known reversal system, and especially the introduction of the tube into the straightening device at the beginning of the extrusion process, It takes a long time and is troublesome. This is because it is difficult to access the central region and the tubes conveyed through the device are partially located in the central region.

[Problems to be Solved by the Invention] Therefore, the problem underlying the present invention is to maintain the kinetic ability of the reversing system, and by means of the kinetic ability, from the tube blowing head in a fixed position to the reversing corrector itself. A controllable guide of the tube to the retractor in position, yet the reversing system has improved stability to avoid disturbing vibrations and vibrations, and at the same time the installation and maintenance of the system and It is to provide a similar type of orthodontic device in which the tube is easy to introduce.

[Means for Solving the Problem] According to the present invention, the problem is solved by the configuration of the correction device according to claim 1. In the above configuration, the reversing and swiveling member of the device is supported on the rotation track, and the inner diameter of the avoidance track is at least equal to the maximum working width of the device. The maximum working width corresponds to the maximum band width of the flattened tube that can be processed in the device. That is, the inner diameter of the rotation track is approximately equal to the length of the diverting roller. Based on the above dimensions, the rotary track assembly constituted by the individual rotary tracks forms a stable structure. Where each orbit is
The rollers are supported by each other only through the intermediate roller body, and the rotary raceway assembly is constructed as an axial bearing due to its supporting force. By virtue of the above construction, obstructive vibrations or vibrations when traveling through a trap or working path mounted on the machine stand are practically eliminated. Moreover, the central area of the reversing system of the orthodontic device, where the vertically high guided tubes approach, is preferably based on the fact that all the rotary trajectories have the same large inner diameter, so that the installation and maintenance Is not occupied by parts of the equipment that may complicate or obstruct or introduce the tube at the beginning of the extrusion process.

Numerous other features and advantages of the invention will be apparent from the dependent claims and the following description in connection with the drawings, which schematically show embodiments of the subject of the invention.

EXAMPLE A synthetic resin film tube 1 was straightened as indicated generally by the numeral 2 with an enlarged round or circular cross section from an extruder equipped with a stationary film blowing head (not shown). Supplied to the device. Enlarged tube 1
Is straightened in the flattened state through the straightening device,
Then, it is supplied to a winding device (not shown). The flattened tube is wound around a storage roll in the winding device. In this case, the tube 1 is guided from the blowing head of the extruder to the upper straightening device 2 along the vertical direction via the relatively long path required for cooling and hardening of the synthetic resin film. Therefore, the straightening device is usually located near the ceiling of the corresponding manufacturing plant.

For this purpose, the straightening device 2 comprises a device stand 3, which is supported on the factory floor by four vertical columns 4, 5, 6, 7. The columns 4 to 7 are horizontal support members 8 above.
On the upper surface of the end region facing the tube 1 inside the support member, the holding frame 9 of the rotary track assembly 10 is held.
Is supported. The rotary track assembly 10 is composed of individual rotary tracks 11, 12, 13, 14 arranged vertically vertically,
Each rotation track has the same inner diameter and outer diameter.
In this case, the inner diameter further matches the inner diameter of the holding frame 9.

The rotating orbits 11, 12, 13 and 14 have roller bodies 15 inserted in the middle.
Thrust bearings that are directly supported by each other or by the holding frame 9 via (balls in the illustrated example) and thus receive a compressive load are configured. Each rotation orbit 11-14 is
They can rotate freely with respect to each other and can be rotated freely with respect to each other. The roller or ball 15 has a rotating orbit 11
-14 or the guide rails 9 are guided with little play in rolling grooves 16 provided on the opposite end faces of the holding frame 9, so that undesired lateral movements of the individual rotary raceways of the rotary raceway assembly 10 in the horizontal plane. Is actually eliminated.

The rotary tracks 11-14 are driven at different speeds by individual motors associated with each rotary track or by a reversing transmission 17 as shown in FIG. For this purpose, the outer periphery of each of the rotary tracks 11-14 is a transmission (in the example shown, in the form of external teeth formed on the outer periphery of the rotary track) for transmissionally engaging with the reversing transmission device 17. Means 18 are provided. The reversing gearing 17 is mounted on the outer side of the rotary track assembly 10 on the device stand 3 in a manner not shown in detail. The reverse gear 17 is a drive shaft 19 which is driven in reverse by a suitable motor (not shown).
And the drive shaft is the vertical axis of the rotary drive assembly 10.
Aligned parallel to 20. A plurality of drive wheels 21 (gears in the illustrated example) are vertically mounted on the drive shaft 19 at intervals in the vertical direction, and each drive wheel has the same rotation track 11 to 14 attached thereto. Planar transmission or external teeth 18
And an intermediate wheel 22 through which the power transmission is coupled. By selecting a drive wheel 21 of suitable diameter, the respective rotary tracks 11-14 are appropriately decelerated via the intermediate wheel 22 in order to obtain the corresponding intended rotational speed. This middle wheel 22
Is the drive shaft 19 and the rotary track assembly in each transmission plane.
It provides the same spacing between the 10 axes 20.

A holding frame 23 is attached to the inner periphery of the lowest rotation track 11, and each holding frame has one vertical support leg 25.
And includes two diametrically opposed peripheral portions 24 with each other. The support legs 25 facing each other are provided with two squeezing rollers 27 rotatable about a horizontal axis and two flattening devices 28 converging towards the rollers.
Is attached. The mounting of the leveling device 26 takes place in the area of the vertical support leg 25, which is guided downwards from the rotary track assembly 10. A guide roller 29 is attached to an area of the vertical support leg 25, which is guided upward from the rotary track assembly 10, so as to be freely rotatable inside the cylindrical inner surface of the rotary track assembly 10. There is. The guide roller 29 is essentially vertically above the roller gap defined by the squeeze roller 27, the first lower diverting roller without the tube 1'contacting the upper edge of the uppermost rotary track 14. It is located at such a height that you can proceed towards 30. Preferably, the generatrix that coincides with the upper apex of the guide roller is above the horizontal plane on which the upper side of the uppermost rotational track 14 is located, which at the same time is of the first lower diverting roller 30. Immediately adjacent to a horizontal plane where there is a bus that coincides with the lower apex. Turning roller
30 is rotatably supported on the free end of a support arm 31, which extends from the upper end of each vertical support leg 25 of the holding frame 23. The rotary orbit 11 is driven by a reversing transmission 17 with a rotational speed corresponding to a reversing swivel of 360 °, ie ± 180 ° from the center position of the flattening device 26. The reversing transmission device 17 is reversely controlled by an appropriate limit switch at the end of each turning motion component of the rotary orbit 11. Correspondingly, each member of the reversal system held by the rotary track 11 (ie the flattening device 26 with the squeezing roller 27 and the flattening plate 28, the guide roller 29 and the diversion roller 30) is identical to 360 °. Perform an inversion swivel motion.

In this reversing system, the turning roller 30 is followed by a first turning rod 32 as seen in the direction of travel of the tubes 1 to 1 '. The turning rod can be constructed in a known manner as a so-called air turning rod with an array of air nozzles for turning the tubes. In this case, the turning rod 32 is non-rotatably attached to the holding rail 33. Each of the holding rails is attached to the outer peripheral portion of the uppermost rotation track 14 so as to diametrically face each other, and the turning rod 32 is non-rotatably fixed between the outer ends 34 thereof. A rotational speed corresponding to a turning angle of 270 ° of the turning rod 32 is applied to the rotary track 14 by a reversing transmission device 17.

The second upper turning roller 35 is attached to the outer circumference of the rotary track 13 by means of a holding rail 36. The retaining rails 36 are again diametrically opposed to each other,
Opposite ends mounted on the outer periphery of the rotary track 13 and guided out of the holding rail.
Between 37, the diverting roller 35 is rotatably supported. A rotation speed corresponding to a 180 ° reversal swivel angle of the direction change roller 35 around the vertical axis 20 of the rotation track assembly 10 is applied to the rotation track 13 by the reversing transmission device 17.

The turning rod 38, which follows the turning roller 35, can be configured as an air turning rod similar to the turning rod 32.
The rotary track 12 is supported by the rotary track 12 via holding rails 39 that are fixed to the outer circumference of the rotary track 12 so as to face each other diametrically. In this case, the turning rod 38 has its both ends fixed between the outer ends 40 of the holding rail 39 so as not to rotate. A rotational speed corresponding to the 90 ° reversal swiveling movement of the turning rod 38 is applied to this rotary track 12 by a reversing transmission 17.

A direction changing roller 41, which is a fixed-position conveying device for discharging the flattened tube 1, is supported by the device base 3 so as to be freely rotatable in a horizontal plane that is essentially the same as the upper turning rod 38. Has been done. For this purpose, the vertical columns 4 and 5 of the device stand 3 are provided with a horizontal upper support arm 42, between which the direction change roller 41 is rotatably supported. .

The turning rollers 30, 35 and the deflection rods 32, 38 are held in the outer region above the rotary track assembly 10 by respective holding rails 31, 33, 36, 39. The outer end regions 31a, 34, 37, 40 of the respective holding rails 31, 33, 36, 39 of the turning rollers and the turning rods or the turning rollers 30, 35 and the turning rods 32, 38 themselves are compression rollers. Interfering circles or limiting circles of various radii are defined during the reciprocal swiveling movement about the axis of rotation 20 of the rotary track assembly 10 at various rotational speeds corresponding to swiveling angles that decrease with distance from 27.
In this case, the circle of interference drawn by the diverting roller 30 of the rotary track 11 is the smallest and is surrounded by the circle of interference of the rotary track 14 with the turning rod 32. The next size interference circle is that of the rotary track 13 with the turning rollers 35, and that of the rotary track 12 with the upper turning rod 38 surrounds all other interference circles. It is the largest circle of interference. Such a relationship is caused by the direction change rollers 30, 35 and the turning rod 3 during the reversing movement of the straightening device.
It guarantees the swivel motions that do not interfere with each other in consideration of various swivel angles of 2,38 and various rotational speeds.

In order to form limit circles or interfering circles of various radii, one of the interfering circles guided around a turning roller 30 mounted inside the lower rotary track 11 with a simple linear holding rail 31 The outer rails 33, 36, 39 are provided with horizontal rail sections 43, 44, 45, whereby corresponding interference circles are arranged correspondingly outwardly, as can be seen especially from FIG. Like As can be seen more clearly from FIG. 2, the diverting roller 30, the diverting rod 32, the diverting roller 35 and the diverting rod 38 are arranged such that their facing busbars are in each case in a common horizontal plane. And are placed one above the other in various horizontal planes. To achieve this, each rail 33, 36, 39 of the rolling tracks 14, 13, 12 comprises a vertical rail section 46, 47, 48 of corresponding height, as clearly shown in FIG.

The roller gap defined by the two squeezing rollers 27 of the flattening device 26 is centrally located with respect to the axis of rotation 20 of the rotary track assembly 10, as is particularly clear from FIG. The rotation axis 20 itself is arranged on an extension of the central axis of the tube 1 moving toward the pressing roller 27. Usually, one of the two pressing rollers 27 is fixedly mounted, and the other pressing roller 27 is pivotally supported by the support leg 25. The swiveling movement is necessary to pull in the tube 1 at the beginning of the extrusion process. By using a pressure medium operating cylinder and a pressure means such as a spring used for this purpose, the pressing force between the pressing rollers 27, that is, the pressing action on the tube 1 which is transferred through the roller gap and flattened. Can be adjusted. The squeezing roller 27, which is fixedly installed, can be driven by a motor (not shown) whose rotation speed can be controlled.

The turning rods 32, 38 have a basic position which extends a distance a from the axis of rotation 20 of the rotary track assembly 10. The distance a corresponds to the radius of a circle around the rotation axis 20 drawn by the orbits of the axes of the turning rods 32 and 38 during the reversing operation, and is calculated by the official turning rod diameter × π / 4. Due to the unrestricted working space provided above the rolling track assembly 10, the pivoting of the turning rods 32, 38 for retracting the tube 1 at the beginning of the extrusion process is not necessary in this construction. Besides, it is self-evident that the turning rods 32, 38 must be sufficiently long to receive the tube 1. In this case, the maximum tilting position of the turning rod (45 ° in the example shown) also determines the position of the diverting rollers 30, 35, as is generally known to those skilled in the art.

During operation of the straightening device, the flattened tube 1'between the squeeze rollers 27 has been shown in FIG. 1 as well as in FIGS.
It is guided through the device 2 corresponding to the dashed line. In this case, the flattened tube 1 ′ is first guided essentially vertically to a guide roller 29 whose axis lies on the axis of rotation 20 of the rotary track assembly 10 and is slightly hugged. In this way, it is guided to the upper direction changing roller 30 over the guide roller. In principle a flattened tube 1 '
It is also possible to guide the squeeze roller 27 directly to the diverting roller 30. However, this would result in an increase in the diameter of the rolling track assembly 10 for guiding the tube 1'through. Such increases are otherwise unnecessary and therefore uneconomical. The tube 1 ′ is a turning rod while holding the turning roller 30.
It is guided to 32, wraps the turning rod again in the same manner, and is guided to the lower surface of the direction changing roller 35 via the upper surface of the turning rod. The tube again again encloses the diverting roller and is guided from the upper surface of the diverting roller to the lower surface of the upper turning rod 38. Tube 1 '
Goes around the turning rod 38 from below and is guided from the turning rod to the direction changing roller 41 in a fixed position on the same plane. The tube has a first
It is guided vertically along the arrow 49 to the winding device in position below. In this case the tube 1'is made up of the turning roller 3
Alternately guided outwardly and inwardly (with respect to the axis of rotation 20 of the rotary track assembly 10) between the 0,35 and the turning rods 32,38. At this time, due to the reversibly swiveling member of the straightening device, the thickness tolerance of the synthetic resin film is evenly distributed along the tube according to the known principle of the reversing straightening device.

FIG. 4 shows the center position of the pressing roller 27 of the flattening device 26. As is clear from the figure, at the central position, the diverting rollers 30 and 35 and the diverting rods 32 and 38 are aligned with each other along the direction of the rotation axis 20 of the rotary track assembly 10. Figures 5,6,7,8 show that the squeezing roller 27 of the flattening device 26 is 90 ° in both directions starting from the center position of Figure 4.
Direction change roller 30, which corresponds to the case of 180 ° turning movement,
The intermediate positions of 35 and the turning rods 32, 38 are shown.

A side edge adjusting device (not shown) for monitoring or measuring the moving state of the tube 1'in the vicinity of the direction changing roller 41 in a manner known per se in order to correct the moving state of the tube as necessary. Related, turning rods 32,38
Will be adjusted. For this purpose, the values detected by the side edge monitoring unit are input to the adjusting unit and evaluated there. The adjusting unit controls the adjusting member which carries out the corresponding adjustment. The adjustment process is well known to those skilled in the art and therefore need not be illustrated or described in detail here.

In the case of the straightening device 2, it is sufficient to adjust the upper turning rod 38 in order to offset the lateral movement of the tube 1'which always occurs for some reason if necessary. For this reason, the distance a that the deflection rod 38 holds from the axis of rotation 20 of the rotary track assembly 10 in the basic position can be varied. The change of the distance a is performed, for example, by moving the turning rod 38 in the radial direction with respect to the rotary track assembly 10. This is clearly shown in FIG. 9, which is a simplified view of the correction device in the operative position of FIG. If the dimension a is reduced as indicated by reference numeral 38 ', the tube 1'will move to the left when viewed along the traveling direction 50. On the contrary, when the dimension a is enlarged, the tube 1'moves to the right. 9th
In order to achieve radial mobility corresponding to the double arrow 51 in the figure, the turning rod 38 is adjustably supported on the rotary track 12 in a manner not shown in detail.

FIG. 10 illustrates another possible way for adjusting the turning rod 38 to influence the movement of the tube, corresponding to FIG. According to this embodiment, the turning rod 38 is supported on the associated rotary track 12 so as to be pivotable about a vertical axis. In this case, the pivoting movement of the turning rod 38 will be superposed in a suitable manner on the reversing pivoting movement of the rotary track 12. For example, when the turning rod 38 is at an angular position of 30 ° at a predetermined time during the turning motion, the turning rod 38 corresponds to the same predetermined time during the turning motion, as clearly indicated by reference numeral 38 'in FIG. The diverting rod is double arrowed by an appropriate control pulse so as to occupy the changed angular position.
It can be turned corresponding to 52. This results in a corresponding lateral displacement of the tube 1 ', again as a side edge adjustment.
